Clomid alone will never bring up your test levels. Whoever your doctor is, they are trying to use outdated methodologies. At 27 years old, a male should be between 700-900 on average. If 337 or 239 is your level at 27 years old, using clomid, you are likely not going to bring your levels up that way. FSH and LH are the hormones needed to stimulate the testis to produce testosterone. Your doctor should have done a test to see what those hormone levels are. If he has not (or won't), get another doctor, period. If FSH and LH are low, then HCG should likely bring them up as long as there isn't anything else wrong, and testosterone production will increase. If they are at normal levels, then you aren't responding to them, and TRT will probably be needed for the rest of your life. I know that's something you probably don't want to hear, but you have to be realistic. You need testosterone to function. If you're like me, and FSH and LH are non-existent, again TRT will probably be needed for the rest of your life. I went to the doctor at 30 with the same levels as you, only I had never touched steroids. Those were my natural levels. I have been on TRT since then, just over 14 years solid. I haven't suffered any ill effects besides acne annoying me from time to time and male pattern baldness (which runs in my family anyway, and I still kept my hair longer than my older and younger brother did). My recent blood tests show I have FSH and LH levels of 0. Yep, zilch, nada. I have to be "on" for the rest of my life. At this point, my wife and I aren't looking to have kids so that's okay, and that's our choice, but we could still have them if we wanted if I went on HCG.
